Find LCM of 642,563,704,274,144 with Prime Factorization
2 | 642, 563, 704, 274, 144 |
2 | 321, 563, 352, 137, 72 |
2 | 321, 563, 176, 137, 36 |
2 | 321, 563, 88, 137, 18 |
3 | 321, 563, 44, 137, 9 |
107, 563, 44, 137, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 107 x 563 x 44 x 137 x 3 = 52291115712
Therefore, the lowest common multiple of 642,563,704,274,144 is 52291115712.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
642 x 563 x 704 x 274 x 144 = 10039894216704
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
642 : 1, 2, 3, 6, 107, 214, 321, 642
563 : 1, 563
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
274 : 1, 2, 137, 274
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,563,704,274,144, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
563:563
704:2x 2x 2x 2x 2x 2x 11
274:2x 137
144:2x 2x 2x 2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 10039894216704/(1x192)
LCM = 10039894216704/192
LCM = 52291115712
Thus, we can understand that the LCM of 642,563,704,274,144 is 52291115712.
